Gildemeister NEF 480 Retrofit

While I was on it, I also cleaned the door.

before:



and after:



now it can dry and be installed next time I'll spend time in the shop. No Idea at the moment how I get this up and in position.

I bought a cheap Ethernet to Modbus gateway and give it a try. If this doesn’t work I still could run a wire. For now it‘s just for fun anyways.

Installed the rear part of the enclosure yesterday

Another step toward finishing this project

Repaired and installed the chip tray. Also the 2nd servo is now in the machine.

Also it was time to bring the Kompressor back to the mill
So now I can start to make some parts to mount the spindle encoder for the lathe.

​

This morning before work I was with the dog in the garden and walked past my lathe and I don‘t know why, but i attached the the belt:

I think we all know why

I am terrible for doing a quick job (in my office clothes) in the morning when I have really gone there just to get my bicycle.

I am still waiting for the new servo drivers to arrive. So no real progress here. Fiddling around with belt tension and installed a lan to Modbus gateway. Next is to wire in the VFD and the servo drives. More or less it is for load but maybe I try to control the spindle by modbus instead of mesa. Not sure yet

Long time ton progress on the lathe. But yesterday the new drives arrived, so I put them in the cabinet and also connected the z-axis servo:

But I didn’t had the palls to power them on.

Instead I disassembled the old spindle encoder to get the axle now I need to figure out how I connect it to the new encoder and how to mount it back on the lathe. Looks like I will spend some time Drawing an aluminium adapter plate and Housing for 3d Printing.

Also I installed the new mpgs After i fired the old ones by connecting them to 20V DC instead of 5V :dry:



So there might come a day where I really can fire this baby up.

But I found two pieces of sheet metal where I have no clue where they came from. It must have been to obvious to make a photo or I was to to exited to stop to make a picture… :whistle:

today I gave the new servo drives a test......

and no smoke, no blowing fuses.



but didn't get the servos to move. I think the z drive should be set up correctly, so I can start to configure linuxcnc for a first test.
I also ordred a nes pulley to get .001 mm increment on the z axis.

then Itried to fit the new encoder in the old encoder and started by making a coupling:



and the first test looked quite promising





but after I mounted everything properly



it would fit, so shortened the old housing and will print a cover for the new encoder later



no I just need to find the old mounting plate again, which I thought I wouldn't need any more :whistle:

Stopped searching and just made one
